Hi Guys new here, I have the common issue of an anti pollution fault coming up on my C5 and then it dies a death, sometimes it starts after 5 mins, sometimes 20mins, so I take it to 2 seperate independent dealers and none of the two them can get the car to communicate with their diagnostic tools. One I know is made by snap on the other am unsure. the car is a 2.0 Hdi C5 VTR mark one (2003) Is their any known problems with these cars? the mechanic did say he had a previous C5 and it did the same thing, can anyone help please? My missus is 36 weeks pregnant and I can't afford for this car to go wrong on me lol :o Many Thanks In Advance Ricky
